Irealsms message send failure badge

Hi guys , I have been using irealms for a while now an I remember that when a message had failed to send I would get a badge on the irealsms app icon to warn me that the message had failed to send ! I don't see this anymore . It is quite annoying as I sometimes reopen the app to see that a message I had sent hours ago had not been sent . Anybody know why the badge doesn't appear anymore on the icon.
Just also noticed that when I send messages from irealsms and it fails I get an exclamation marked badge on the native (sms) messages icon but not on the irealsms icon ??
